Ammonium Carbonate Extra Pure
Original price was: $ 18.00.$ 17.34Current price is: $ 17.34.
Ammonium Carbonate Extra Pure is a high-quality, white crystalline solid widely used across various scientific, industrial, and food-related applications. Manufactured to stringent purity standards, this compound is ideal for laboratories and processes that demand high-grade reagents. With its characteristic ammonia-like odor and ability to decompose upon heating, ammonium carbonate plays a versatile role in both chemical reactions and physical processes.
In aqueous solution, ammonium carbonate breaks down into ammonium bicarbonate and ammonium carbamate, further releasing ammonia (NH₃) and carbon dioxide (CO₂) upon heating. This property makes it especially useful in applications that require controlled gas release or temporary pH modification.
Ammonium Carbonate Extra Pure
